Oo, normal na normal yan! Lalo na sa breastfed babies, marami sa kanila mag-poop right after feeding or even during feeding dahil sa sucking reflex nila, parang automatic lang. A few of my mum friends said their babies did this for months, at nag-normalize lang after 6 months or so, so don't worry ka muna. The important thing is na ang poop color at consistency niya ay yellowish at soft (parang mustard), at na-gain siya ng weight nicely, kasi yan ang sign na nakukuha niya ng enough milk.
